VO2 max not populating anymore

[ftaok]

Has anyone else had this problem. I was regularly getting the VO2 max to populate in Health using various workout/app combinations (AW-outdoor walk, Nike+ outdoor/indoor run, iSmoothrun outdoor/indoor run). It just worked fine.

However the last reading to populate was my run on 11NOV. I've gone on several runs (but no outdoor walks) since then, VO2max hasn't populated at all. All runs have been done on iSmoothrun with the GPS on.

Not sure why it's not working anymore.

I was wondering the same thing. Mine stopped populating for about two weeks recently. It seems to have started again two days ago - worked on 11/17 and 11/18, haven't done a workout today. No real rhyme or reason I could figure out. My workouts/workout intensity did not change during that time it wasn't calculating. Only thing that came to mind that has changed is the weather - much colder here - but that shouldn't really have any impact (right?).

hmmm. It's gotten a lot colder here as well. Not sure if it affects it or not. I'll be sure to do a brisk walk tomorrow at work using the built in workout app.
